Definitions

  • the present invention relates to a modular extraction column.
  • An extraction column is used in a variety of chemical plants, as major equipment in an extraction process.
  • the extraction column performs extraction by allowing a heavy phase of higher density to be input into a top head thereof to flow downwards while allowing a light phase of lower density to be input into a bottom head thereof, such that the two phases continuously come into countercurrent contact.
  • Such extraction columns are fabricated in a variety of diameters and heights according to the properties of fluid in processes. Inner structures having a variety of shapes may be added to increase the contact area between fluids as required.
  • Korean Patent No. 10-1522771 (patented on May 26, 2015 ) disclosed a vertical liquid-liquid separation apparatus based on the principle of a mixer-settler apparatus.
  • the disclosed apparatus has superior acid/base resistance, with parts thereof being able to be easily operated.
  • a typical extraction column as disclosed in the prior-art document has an integrated structure, in which the height of the column is determined using a specific standard, such as height of transfer unit (HTU) and number of transfer unit (NTU).
  • HTU height of transfer unit
  • NTU number of transfer unit
  • the present invention has been made keeping in mind the above problems occurring in the related art, and the present invention is intended to propose a modular extraction column that can be easily fabricated and constructed, and after construction, allows for easy maintenance, such as replacement of a damaged structural part and removal of contaminants.
  • the modular extraction column facilitates the assembly and construction thereof, since the modular extraction column includes the end blocks and the body block consisting of the column modules.
  • the inner structure is provided the shape of a cartridge for each column module and the cover is provided in the open area of the column module. It is therefore easy attach or detach the inner structure to or from the column module, thereby advantageously facilitating maintenance, such as replacement of a damaged portion of the inner structure or removal of contaminants.
  • the body block 20 is a multi-stage structure, with both ends thereof being coupled to the flanges 110 of the end blocks 10 in a surface contact manner.
  • the body block 20 includes column modules 210 and covers 220.
  • the body block 20 is formed by stacking the column modules 210 having a predetermined length on one another, instead of having an integrated structure.
  • each column module 210 includes a first module flange 212 and a second module flange 213.
  • An accommodating portion 211 having a predetermined area is formed within the column module 210.
  • the column module 210 has an open area 214 in one side. The open area 214 is able to communicate with the accommodating portion 211 within the column module 210.
  • the length of the column module 210 may be adjusted considering the ease of manufacturing, fabrication, and maintenance according to the space of construction.
  • the first module flange 212 and the second module flange 213 are provided coaxially on the opposite ends of the column module 210 to face away from each other.
  • the first module flange 212 and the second module flange 213 may be arranged to abut against one or both of the flanges 110 of the end blocks 10 or the second module flange 213 and the first module flange 212 of the adjacent other column modules 210 to be coupled thereto in extended areas.
  • the dimensions, shape, and size of the first module flange 212 are the same as those of the second module flange 213 and, furthermore, the flange 110, such that the column module 210 can be disposed without being restricted in the orientation thereof.
  • the end blocks 10 and the body block 20 can be coupled to each other using the flanges.
  • the end blocks 10 and the body block 20 may be stacked on and coupled to each other via gaskets 40.
  • the gaskets 40 are provided in connecting portions between the flanges 110 of the end block 10 and the first module flange(s) 212 and the second module flange(s) 213 of the body block 20, thereby preventing leakage in the connecting portions.
  • FIGS. 5A to 5E are perspective assembled views schematically illustrating examples of the inner structure 310 according to the exemplary embodiment of the present invention.
  • the internal structure 310 has the shape of a cartridge that is introduced through the open area 214 and is seated in the accommodating portion 211 adjacent to the open area 214.
  • the internal structure 310 is accommodated in the accommodating portion(s) 211 of the body block(s) 20 and functions to distribute fluid, thereby increasing the contact area between fluids.
  • the structural body 320 may be formed by stacking a plurality of structural sections having the same shape on one another in the top-bottom direction to distribute a fluid in order to increase the contact area between fluids.
  • the structural body 320 may be fabricated as one of a structure including perforated plates 321, a structure including sieve trays 322, or a structure including baffle trays 323.
  • a second embodiment of the inner structure 310 may include the support 330 and packing 340.
  • the second embodiment of the inner structure 310 may further include a packing holding film 350.
  • the support 330 may include a plurality of support plates 332, the edges of which are coupled to each other to form a rectangular horizontal cross-section, such that a hollow inner area is defined within the support plates 332.
  • the packing 340 may be accommodated in the hollow inner area and may be coupled to the support 330.
  • the packing holding film 350 may be a structure disposed on one or both sides of the support 330.
  • the packing holding film 350 may allow fluids to pass therethrough while supporting packing 340 such that the packing 340 such is not drained by flows of fluid.
  • the packing holding film 350 may a mesh structure having a predetermined size, this is not intended to be limiting.
  • the first embodiment and the second embodiment of the inner structure 310 may be determined suitably according to process characteristics.
  • the modular extraction column 1 disclosed with reference to FIGS. 1 to 5E is not limited to the specific length or shape but is only provided for a better understanding of the present invention to those skilled in the art to which the present invention belongs.
